# Some versions of the info tool will emit single quotes as directional
# quotation marks (i.e. U+2018 and U+2019). This causes problems because awk
# on MSYS* / MinGW* / Cygwin* systems does not handle UTF-8 encoded input
# properly. (Apparently, it's some weird Windows code page thing.)
# Using the C locale makes info emit the apostrophe character for single quotes.
# Since that is ASCII, affected versions of awk do not have a problem with it.
# None of this is an issue on non-Windows systems since their versions of
# awk are not affected.
